According to market feedback, due to the high cost of the current BMS battery management system, many customers actually need to monitor the voltage of each battery, the total load current, and the ambient temperature of the small battery pack. The main application scenarios are solar power supply system, base station backup power system, and small computer room backup power system. application system scenario diagram is as follows.
